My laptop gets too hot when rendering in cycles
I have the same laptop, and it does indeed get hot. But this isn't really an issue specific to Cycles or even this laptop, any CPU / GPU heavy computation that has good multithreading will do it, and laptops often just aren't made to run cool under such loads.

I suggest to use CPU rendering with a lower number of threads like 2 or 3 instead of using an automatic number of threads. This mobile GPU isn't faster than the CPU in most scenes anyway. Cycles doesn't have an explicit way to specify using fewer GPU cores, though you could try decreasing the tile size to make it render slower and hopefully get it to run cooler as well then.
